As for cold plate thickness, BillA has made some recommendations for the thickness.
Also, I thought the recommended pressure was 300ish pound, not psi, wich is the same, I think, as about 75psi (with 50x50 TEC)?? The americain's unit system is killing me!

making the block is not complicated, what is complicated, as Jaydee pointed out, is making a proper or good design.

I thought it was PSI. Could be wrong. If it is pounds then 4 screws should be good enough but more the marrier. I got a lot of experimenting to do on this yet.
